Update creating-a-static-mockup

I'm currently going through the tutorial with some buddies - noticed that after pasting in the html into the `index.html` file, adding the styles and bg image - the page was broken.

After comparing in FileMerge, I noticed that the html was wrapped in handlebars tags:

line 9: `<script type="text/x-handlebars" data-template-name="todos">`.

&&

line 60: `</script>`

However, at this point in the tutorial - there is no inclusion of the handlebars or ember files - preventing the content from displaying on the page.

Solution: Removing the handlebars tags, page loads up fine!
